B1119 Code - Left Air Bag Satellite Sensor
Quick Answer
When the Air Bag Diagnosis Sensor Unit (ACU) define the both signal voltage of the “G†sensor and the Safing sensor to be that of the collision which exceeds the specified level, the driving circuit switches on and feeds the electric ignitor of both the side air bag and curtain air bag. Common causes include Faulty Left Air Bag Satellite Sensor, Left Air Bag Satellite Sensor harness is open or shorted, Left Air Bag Satellite Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service
- Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
- Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
- Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
- Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.
Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
